Gunshot sounds are made up on the fly by combining lots of other sounds. There are no "MTAR_firing" sounds or things like that. If you want that I think you will have to record from in-game.

That said, I am by no means an audio-wizard so take what I have said with a grain of salt. The above is just what I have gathered from this and similar threads.

I think you know this way better than I do, would you care to lay down the truth?

You pretty much hit the nail on the head.
to rebuild gun shot sounds you would also need to use some scripts to extract all the game data and convert ebx files to text files. then all the information needed is contained in the converted text files.
Frankelstner(the guy who made all the tools we use to extract everything) explains it best here Frostbite 2 Audio Decoder - Official BF Editor Forums - Page 2. Really that whole thread is really informative and worth a read.

I have them all ripped. I just gotta convert them all to mp3 and upload them. At some point over the weekend I will get them uploaded. :]

Why bother uploading the Naval Strike audio files, there's like hardly anything useful there. There are no sfx audiofiles for the maps, only for the wavebreaker submarine 'levolution' and nothing useful in the ambients except for the ghost sounds.
